Specification of Letters Patent.

' Patented July 3, 1906.

Application iiled May 19, 1905. Serial No. 261,249.

T0 all whom it may concern:

Be it known that I, WILLIAM S. WAKELEY, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented certain new and useful Improvements in Pipe-Cutters, of which the following is a speciiication.

This invention relates to improvements in implements for cutting pipes or round rods; and the especial object of the improvements which form the subject-matter of this application is to produce a pipe-cutter that may be adjusted to pipes of greatly-varying diameters that will firmly plant the device during the cutting operation, that will make a clean cut leaving no ragged edge, and that will entirely sever the pipe by the cutting operation.

Other objects of general utility are secured through my improvements, as will be apparent to those skilled in the art.

In the accompanying drawings, whichform a part oi this application, I have shown a preierred embodiment of myinvention in the following views.

Figure 1 is a side elevation of a pipe-cutter constructed according to my invention. Fig. 2 is a top plan view of said pipe-cutter. Fig. 3 is a vertical section on the line 3 3 of Fig. 1. Fig. 4 is an enlarged detail of the cutting elements proper. Fig. 5 shows the clampingjaws and their attached parts, and Fig. 6 is a front end view of the cutting element proper.

Referring to the details of the drawings, A A represent two vertical clamping members or jaws which have their inner edges inwardly inclined, so as to adapt them to grip the surface of the pipe F. The members A are bolted at their lower ends to a horizontal bar D and between their upper ends have secured a fin er or pin a', which serves as a catch or locking element.

B B represent two clamping members which are bolted together with a space therebetween and have their inner ed es formed similarly to the opposite edges of t e complementary members A A. -Between the lower portions of the members B a slideway is provided ior a flat metal bar D. Bolted between the members B B are twolat plates C C, the lower portion of which is cut away to provide a slideway for the bar D, and the upper ortion oi which is cut away to provide a s ideway for the knife-holder to be described. To the outer end of the bar D is bolted a socket d', into which is screwed a suitable handlebar d2. Between the upper ends of the clamping elements B B is bolted a slotted block b, on which are pivoted Hat bars E E, which, together with the socket e3, to which they are secured, and the handle e4, which is screwed into the socket, form a lever which is adapted to lock on the members A A through the engagement of the finger a with pins e, which extend transversely between the bars E. Bolted to the rear edge of the plates C C is a block c', in which a threaded opening is formed to receive the screw-bolt c2, the inner end of which engages the plates c3 c3, which are connected by screws land are recessed to form a housing for the cutting-knife c, the latter being held between said plates by frictional contact With the inner sides of said plates. A suitable crank c5 is secured to the bolt c2, and by turning the same said bolt and the knife-holding plates c3 will be advanced or retracted in the slideway between the plates C C and the clamping members B B, thus providing the necessary adjustment for said cutting-knife c4.

A pipe F, inserted between the jaws A and B, will be frictionally embraced by the latter, and when they are as close as they can be brought by manual operation the lever formed by E, e3, and et will be brought down over the finger a, whereupon the latter will engage one of the pins or iit tightly between two of said pins e', and thus lock the pipe in position. Ii necessary to eiiect a close en- -gagement between the finger a and the pins e', longitudinal adjustment of the bars E may be effected by screwing in or out the setscrew b2, which has a threaded engagement with the block b', so that its inner end bears against the bolt which holds the block and which passes through the slot in the block.

, When the pipe has been locked in position, the point of the knife c4 is brought into close engagement with the periphery of the pipe by driving the screw c2 forward, whereupon the device as a whole will be revolved around the pipe in the usual manner, the screw c2 being tightened from time to time as the pipe metal is cut away by the knife c4. apparent that as the point of the knife ci is worn away by rinding and use the knife may be adjusted ongitudinallyinits bearings in the plate c3. For purposes of description the jaws A may be designated as fixed jaws, while the jaws B may be termed slidable" jaws, though as a matter of fact both japlvs are slidably mounted relative to each ot er.

vIoo

It will be IIO Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cutting-tool of the class described, a bar having a handle secured at one end thereof and a clamping-jaw fixed on the other end, a clamping-jaw slidably mounted on said bar, a cutter slidably adjustable in said sliding jaw, and means for locking together said fixed and sliding jaws.

2. In a cutting-tool of the class described, bar, a clamping element secured to said bar, a clamping element slidably mounted on said bar, a cutter slidably adjustable on said sliding element, means for adjusting said cutter, and adjustable means for locking together said iXed and slidable clamping elements.

3. In a cutting-tool of the class described, a bar, a clamping element secured to said bar and having a pin projecting therefrom, a clamping element slidably mounted on said bar, a cutter adjustably mounted on said slidable element, means for adjusting said cutter, a lever pivoted on said slidable element, and means on said lever adapted to en-l gage said pin and lock said clamping elements together.

4. In a cutting-tool of the class described, a bar, a clamping element secured to said bar and having a pin projecting therefrom, a clamping element slidably mounted on said bar, a cutter-holder adjustably mounted on said slidable element, means for adjusting said holder, a cutter adjustably held by said holder, a lever adjustably pivoted on said slidable element and means on said lever adapted to engage said pin and lock said clamping elements together.

5. In a cutting-tool, a bar, a clamping member Xed on one end of said bar, a second clamping memberslidably mounted on said bar, a cutter adjustably mounted on said slidable member, a lever pivoted on said slidable member and means -i'or locking said lever to said iXed clamping member.

6. In a cutting-tool, a bar, tWo clamping members arranged on said bar, a cutter ade justably mounted on one of said clamping members, a lever pivoted on one of said clamping members and adjustable means for locking said lever to the other clamping member.

7. In a cutting-tool, a bar, tWo clamping members arranged on said bar and adjustable relative to each other, a cutter adjustably mounted on one of said clamping members, a lever adj ustably pivoted on one of said clamping members, and means for adjustably locking said lever to the other clamping member.

In testimony Whereor1 I afliX my signature in presence of two Witnesses.
